What I got from this is that you guys are compiling against a kernel source
tree that has at least had "make depend" on it with a .config that specifies
SMP or UP.  My reference kernel source is completely unbuilt and unconfigured.

Here is what I've done to build the source:


1. Copy in some stuff from the heartbeat project:

cd heartbeat-0.4.8m/heartbeat
cp heartbeat.h hb_api_core.h hb_api.h ha_msg.h ../../dlm/include
mkdir ../../dlm/lib
cp libhbclient.a libhbclient.so ../../dlm/lib
cd ../stonith
cp stonith.h ../../dlm/include


2. Create a top level Makefile:

all:
        make -C dlmcccp
        make -C dlmdk dlm_proto.h
        make -C dlmdk
        make -C dlmdu
        make -C libdlm api_proto.h
        make -C libdlm


3. Remove read-only files to allow for auto generate:

    rm dlmdk/dlm_proto.h libdlm/api_proto.h


4. Modify Makefile to reference desired linux kernel source:

    diff dlmcccp/Makefile.org dlmcccp/Makefile
40c40
< INC   = -I. -I../include
---
> INC   = -I. -I../include -I../linux/include
    diff dlmdk/Makefile.org dlmdk/Makefile
49c49
< INC   = -I. -I../include -I-
---
> INC   = -I. -I../include -I../linux/include
    ...
    (NOTE: -I- gets in the way of heartbeat includes!)


5. Add library path for heartbeat, and make rm of dlm_heartbeat.c automatic:

    diff ./dlmdu/Makefile.org ./dlmdu/Makefile
64c64
< INC   = -I. -I../include -I-
---
> INC   = -I. -I../include -I../linux/include
71c71
< LDLIBS = -lhbclient -lpthread
---
> LDLIBS = -L../lib -lhbclient -lpthread
77c77
< INC   = -I. -I../include -I-
---
> INC   = -I. -I../include -I../linux/include
133c133
<       rm dlm_heartbeat.c
---
>       rm -f dlm_heartbeat.c


6. Setup compiling environment

export UP=up
export CLUSTINT=direct
export CLUSTMGR=heartbeat
ln -s ../linux-2.2.18 linux
make
